58xx power draw?

So apparently this is the power draw for the new 58xx cards

This seems very low to me since apparently my 8800gt has an idle of 128 and a peak load of over 220.

I'm assuming there must be two different forms of measurement going on here.

Also if the 5870 only requires 18w more than the 5850 and considerably less than my 8800gyt how come it requires 2 power connectors?

This is probably a really noobish set of questions but I find it pretty confusing.

The graph shows full PC load, including the various graphics cards, and the 58** figures are probably for the card only, I reckon.

I just hope that even if it does use a lot of power that it isn't too noisy and it doesn't melt my motherboard :)

+1.

8800GT uses nowhere near that amount under peak load.

8800gt uses 35W idle, 78W load

more intrestingly
4850 41W idle, 110W load
4870 65W idle, 130W load
